Product Overview
Underboost, shaft noise, oil at the compressor outlet, smoke, or a damaged turbine can lead to turbocharger replacement after charge-air leaks, wastegate control, sensors, exhaust restriction, lubrication, and engine condition are tested. Part number 18900-6A0-003 identifies the complete turbo assembly—not a stand-alone control solenoid.
Turbo failures are often caused by oil starvation, contamination, foreign-object damage, or crankcase-pressure problems. Find the cause, clean the intake and charge pipes, and verify oil feed and drain flow before installing the new unit.
